Noctilucent clouds exist in Summer high up in the mesosphere, at an altitude of 76 to 85 km. They occur when temperature in the mesophere reaches its annual minimum below -120°C. NLCs usually are found in the polar regions, but, also in mid latitudes. When the sun is only slightly below the horizon in summer in mid latitudes, the NLCs are still illuminated by sunlight while it is already dark below. Then they become visible as whispy silvery clouds against the dark night sky. In Hannover, where I took the images, they can usually be seen between early June and late July. Best is the time when the sun is between 8° and 12° below the horizon.

Many cirrus clouds from an approaching front were about and limited view of the NLCs. Shortly after 21:30 UTC the whole display was behind clouds.

I had set my alarm clock to 1 UTC (3 CEST). It woke me up on time and I turned it off. However, it did not get up! At 2:30 UTC I woke up and immediately had a look for NCLs even though it was too late. They must have been fairly bright as some were still visible. They faded shortly afterwards and I went to bed again...

After a two day break, there were NLCs faintly visible low in the NNE shortly before 1 UTC. So I decided to go to the Lindener Berg, where there is a nice view across the city. The display developed beautifully and ralmost reached into the zenith, before dawn got to bright. The moon, Venus and Mars added nicely to the scene.

The evening was very clear and with a friend I went to a field track on the western slopes of the Gehrdener Berg. Michael finally discovered the first NLCs of the evening at about 20:30 UTC. It was a nice structured display which got fairly bright towards the end.

The next morning was not much better than the evening - many clouds and, additionally, fog. I drove north to the location near Resse where I had been two days earlier. However, too much fog there. So I headed east on L383 and found a spot with only little fog just after Mellendorf. Still, there were too many clouds. I took a few photos and then went back home. These NLCs were very bright!

After watching Iceage 3 and leaving the cinema I was surprised that a thunderstorm was moving across Hannover. I had expected fairly clear skies instead. So there did not seem to be a chance of watching NLCs. On the way home I could see some breaks in the clouds towards the south west. So I decided to go to my observing location near Gehrden south west of Hannover. On the way there it cleared up a little and I could immediately see NLCs very high in the sky, and some bright ones covering all of the western and south western horizon. So I quickly stopped on a field track near Benthe-Sieben Trappen. It was a beautiful display. However, more clouds moved in from the south west which ended my observations shortly after 21 UTC. Back home I could still see some very bright NLCs in small breaks in the clouds. So I hoped for the next morning.

After the fantastic NLC display in the morning another one followed in the evening. From my experience the evening before, where trees had blocked the view near the horizon, I decided to go to a field track west of the Gehrdener Berg. From home I had already seen the NLCs. It was a beautifully structured field slowly moving from east to west on the northern horizon. It gradually disappeared as the sun went further below the horizon. Later some more NLCs became visible very low in the north west. DivX codec required for movies.

After I had returned home from the evening observation, I had a first look at the images. The NLCs had been very bright so I hoped for another nice display in the morning. And I was not disapointed! Already on the way to a dark spot near Resse (north of Hannover), I could see that the NLCs were bright and active again (01:00 UTC). The sky was clear, only some fog was spreading across the meadows and fields, illuminated by the Moon. Above this the beautiful NLCs - what a scene! All in all one of the best displays I have so far observed, especially because of the low fog. After about 01:50 UTC the fog became pretty dense. However, there were still some spots behind some small forests where the sky remained clear. After about 02:30 UTC it became too bright for the NLCs and I went home. DivX codec required for movies.

Many clouds were in the sky and is was quite hazy, so I realized too late that NLCs were already visible. I left home shortly after 21 UTC and arived at my chosen location north of Heitlingen (NW of Hannover) only at 21:30. Most of the NLCs had disappeared by then. Some faint ones were visible towards the WNW and many clouds obscured much of the northern horizon. However, when the clouds finally moved away, a beautiful and bright field of NLCs was revealed in the NW (up to 10° elevation). It slowly faded while another field appeared very low in the north (<4° elevation).

A large scale NLC display in the morning. A beautifully structured field of NLCs moved in from the north. However, many clouds were about so that I had to leave home and drive to a better location. Unfortunately, the Klappenburg Bridge across the river Leine was closed so that I had to take a long detour. When I finally arrived in an OK spot near Heitlingen, it was already quite late. I had to relocate again due to clouds and ended up some 3.5 km north of Resse only shortly before 2 UTC. Anyway, the NLC were nice and worth the drive. When I had just got back home it started to rain. So I was pretty lucky in the end. DivX codec required for movies.

Fantastic NLC display in the morning. A bright and beautifully structured field of NLCs moved in from the northeast. Observation from 00:45 to 02:35 UTC, until dawn became too bright.

Some faint NLC were visible in the evening. Later some beautifull wave structures appeared very close to the horizon towards the north east. Haze illuminated by the bright city lights impeded observation. Therefore, I decided too late to go somewhere north of the city. I found a nice spot near Heitlingen where the NLCs were nicely visible. However, the bright wave field quickly faded and I was already about to leave when I noticed spme very faint NLCs higher above the horizon. And the higer the sun rose the more it became clear that this faint veil covered the whole sky! A bit after 2 UTC the last NLCs faded from view. DivX codec required for movies.
